The invention provides a power grid overhauling plan compilation method based on graphic operations. In the method, firstly a picture element and standard data mapping mechanism is adopted, heuristic search is triggered by virtue of the graphic operations and standard power grid overhauling basic data with uniform format are generated through searching in a device mapping base; and on the basis, tie line analysis is triggered by the graphic operations, the generated overhauling basic data and a power grid overhauling knowledge base are correlated, and the data adjustment and the final overhauling plan compilation are interactively completed under a graphical environment.
